1026 Manual Ivie Technologies, Inc. __________________________________________________________ Preset Port Configure (Edit Pull-Down Menu): There are sixteen presets available on a 1026, but only eight sets of contact closure terminals to be used for activating presets. What if more than eight presets requiring contact closure activation are necessary? The Preset Port Configure utility is intended to provide this function. There are 256 different preset port switch patterns available which can be used to activate presets by various contact closure combinations. The Preset Port Configure pop-up window with the standard factory default configuration is shown in Figure 29 below: The “Default” Preset Port Configure Pop-up Window Figure 29 The Preset Port Configuration is set in a default position when a 1026 is shipped from the factory. In the default configuration, Preset 1 will be activated when Port Terminal 1 is grounded, Preset 2 will be activated when Port Terminal 2 is grounded, etc. Important Note: The Preset Port is not field configurable via the 1026 software. Custom Preset Port configurations are available from the factory. Contact Ivie for further information on custom Preset Port configurations. Set Unit and Channel Names (Edit Pull-Down Menu): The 1026 software allows each 1026 on the network to be given a meaningful name. This makes it much easier and very intuitive to select and work with individual units. A digital signal processor with the name “Exhibit Hall” is much more meaningful than 1026 at address number 5. To give a 1026 a name, and/or give names to the individual inputs and outputs, select the Set Unit and Channel Names utility. A box will appear with the current or default unit name and channel names. Type in the desired name and press the OK button. To exit without making any changes, press the cancel button. Lock with Password (Edit Pull-Down Menu): Password security is available for the 1026, as well as for other AudioNet® products. The Lock with Password utility provides a pop-up window which allows the entry of a four digit password for locking units. Characters cannot be used as part of a password, only digits between 0 and 9. All four digits must be used. The assigned password is retained in the 1026 unit Page 33

Set Unit IP Address (Edit Pull-Down Menu): When there is more than one 1026 on the network simultaneously, each unit must have its own unique address. 1026s are shipped from the factory with a default unit address. When the 1026 software starts up, it scans the network for units and lists their addresses. If there is more than one 1026 on the network, they will automatically be assigned different IP addresses. Although this process is automatic, selecting Set Unit IP Address will force the software to reinitiate the scan process, so if units have been added to the network after the software was started, they will be found. Automixer Pull-Down Menu The Automixer Pull-Down Menu contains two items: “ALC Levels”, and “Setup Options”. ALC Levels (Automixer Pull-Down Menu): It would be beneficial to discuss the ALC of the 1026 in some detail. All 1026 inputs are equipped with an automatic level control (ALC) which can be activated or deactivated. Each channel is independent of the others, so ALC can be active for one channel only, or for any combination of channels. When properly set up, the ALC will absolutely not send a system into feedback. Conversely, it is not magic. It cannot increase system gain before feedback. Perhaps the ALC is easiest thought of as a remote control that has had its gain trimmed such that it can turn a system up to just below feedback, but not any higher. No matter how hard the operator of the remote control tries, he cannot turn up the system far enough to go into feedback. He can turn down microphone users that are too loud into the room, and turn up those who are too soft. However, he cannot turn up someone who is soft spoken any louder than just below system feedback. That is the maximum gain available - the system limits have been reached - and if the person is still not loud enough, he must speak up or get closer to the mic, or both. The 1026 ALC functions in exactly this manner. It replaces the operator of the “remote control” in the analogy above. The “level control” the ALC uses is the input VCA. When the Automatic Level Control is turned on, it will try, by controlling the VCA, to hold a constant level (target level) at the output of the VCA. The ALC has a maximum range of 32dB and the mixer or input expander can automatically adjust level over that range in order to keep the sound level in the room constant. The ALC factory default setting turns the level down (attenuates) at a rate of 10dB per second (20dB in two seconds). It turns the level up at a rate of 2.5dB per second (20dB in eight seconds). These rates work very well over the vast majority of application requirements, but can be altered when necessary. Again, the maximum range of the ALC is 32dB. It operates over that range to try to keep a constant “target” level at the output of the VCA. The signal which the target level maintains can actually be measured at the “Channel Direct Out”. The target level is adjustable from -10dBu to +4dBu in 1dB steps. The factory default setting for the target level is -10dBu. Figure 30, on the following page, graphically presents the 32dB range of the ALC and its function over that range: Page 34
